AT89系列51单片机系统的低功耗设计

摘要

出于低功耗应用的需要，分别从硬件和软件的角度，提出一系列针对AT89系列51单片机系统设计的低功耗设置方法。测试结果表明，这些方法能有效地降低系统的功耗，也可为其它类型单片机系统的低功耗设计提供参考。%For the needs of low-power applications , a series of low-power setting methods about AT 89 series 51 MCU system was presented, respectively, from hardware and software perspectives .Test results proved that these methods can effectively reduce power consumption of the system .They also provided a reference for low-power design of other types of MCU system .
